Creates a link to a file or a directory
Creates a link to a file or a directory. This method tries to create a link to a file/directory on the file system, e.g. a symbolic link and Windows Shortcut links. It depends on operating and file system (and argument settings), which type of link is finally created, but all this is hidden internally so that links can be created the same way regardless of system.
# S3 method for default createLink(link=".", target, skip=!overwrite, overwrite=FALSE, methods=getOption("createLink/args/methods", c("unix-symlink", "windows-ntfs-symlink", "windows-shortcut")), ...)

TRUEand a file with the same name as argument
linkalready exists, then the nothing is done.
TRUE, an existing link file is overwritten, otherwise not.
Returns (invisibly) the path or pathname to the link.
If no link was created,
NULL is returned.
Required privileges on Windows
In order for
method="windows-ntfs-symlink" (utilizing executable
createWindowsShortcut()) to succeed on Windows,
the client/R session must run with sufficient privileges
(it has been reported that Administrative rights are necessary).
